ESP32 WS2812B Music Visualiser Kit with ESP32 + LED
ESP32 Music Visualiser Kit — Build a Sound-Activated LED VU Meter
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Watch LEDs bounce to the beat of your music. This kit uses a MAX9814 microphone to capture sound and an ESP32 to drive 8 WS2812B LEDs in a VU-meter pattern. Assemble on the breadboard, upload the code, and your music becomes a colourful light show.
What You'll Build
You'll build a sound-reactive LED display. The onboard mic picks up music and the 8 LEDs light up progressively, just like a professional audio meter. It's a fun way to learn about audio circuits and create a colourful desktop gadget.
What You'll Learn
- How to interface an analog microphone amplifier with a microcontroller
- Programming individually addressable RGB LEDs (WS2812B) using digital signals
- Reading analog sensor values and mapping them to visual outputs
- Circuit assembly on a breadboard without soldering

Built and Backed by Compoden
Every Compoden kit comes with an AI build companion — scan the QR code on the box, with WhatsApp and email backup. We’ve spent 10 years supporting makers and schools in India. If a part fails due to a manufacturing defect, we replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to get the AI companion, or WhatsApp us. We'll guide you through any issue.
Does this kit require any soldering?
No soldering. Everything plugs into the breadboard — great for young builders with adult help.
Can I use this visualiser with any music source?
Yes, the mic hears any music from a speaker or phone. Play music nearby and watch the lights react.
Can I expand the project with more LEDs later?
Yes. The ESP32 can control more LEDs; just update the code and power supply.
MAX9814 mic amplitude drives 8 WS2812B LEDs in a VU-meter style bounce pattern to music.
